roeLn-notr AND HOLDER.

Specification of Letters Patent.

Patented Nov. 23. 1920.

Application filed. June 7, 1919. Serial No. 302,528.

T 0 all whom it may concern.

Be it known that I, THOMAS. Down, a subject of the King of England, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Toggle-Bolts and Holders, of which following is a specification.

This invention relates to improvements in toggle bolts and more particularly to a means for securing a toggle bolt in position prior to applying the nut thereto.

Another object of the invention resides in the provision of a bolt the head of which consists of pivoted arms which normally tend to spring outwardly and are designed to engage the inner face of a support in order to hold the bolt against withdrawal. A further object of the invention is to provide a bushing which is adapted to be threaded upon the bolt and counter sunk in the outer face of the wall in order to prevent said bolt from being displaced while anarticle is being applied thereto.

With the above and other objects in view as will be come apparent as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as will be fully set forth in the following specification, claimed and illustrated in theaccompanying drawings in which:

Figurel is a fragmentary sectional view through a wall illustrating the bolt being applied thereto. p

ig. 2 is a view similar to Fig. 1 1llustrating the bolt after having been placed in position and showing the bushing in place. Fig. 3 is a view similar to Fig. 2 illustrating the use of the device when supporting an outlet box.

Fig. 4 is an end view of the bolt and Fig. 5 is a fragmentary side view partly I in section of the bolt.

Referring to the drawings in detail 1 designates a wall provided with an aperture 2 for the reception of the bolt. The bolt above referred to. is designated by the nu: meral3 and comprises a shank 4, the upper end of which is provided with pairs of laterally extending pa'rallel ears 5 between which arms 6 are pivoted. Surrounding the pivots 7 are coil springs 8, the arms 9 of which engage pins 10 on the arm 6 while the extensions 11 of said springs engage the shank in the manner illustrated in Fig. 5. It will thus be seen that the arms 6 normally tend to spread into the position illustrated in Figs. 2 to 5 inclusive.

The bolt is inserted in the wall in the manner illustrated in Figs. 1 and 2 after which the bushing 12 is threaded onto the bolt as will be clearly seen upon reference to Figs. 2 and 3. The bushing constitutes a cylindrical body 13 formed adjacent one end with a, flange 14. which extends laterally and'is adapted to be received in a countersink 15 in the wall. The flange is provided with a transversely extending slot 17 for the reception of a screw driver blade by means of which the bushing may be tightened upon the bolt.

After the bolt is positioned in the manner illustrated in Fig. 2 with the bushing 12 holding the same against accidental displacement as-much of the shank is cut off as may be desired in order to prevent the same from projecting for any great distance be 0nd the wall.

t will be obvious that after the end of the shank has been removed, an article such as the outlet box 18 may be slipped over the end of the bolt in the manner shown in Fig. 3 and the securing nut 19 may then be threaded upon the bolt in order to firmly clamp the article against displacement.

From the foregoing it will be obvious that the article 18 may be removed at will by loosening the nut 19 and any danger of the bolt being forced through the opening to such an extent as to render the reapplication of the article and nut will be eliminated.

While in the foregoing has been shown and described the preferred form of this invention it is to be understood that certain minor changes and construction, combina- -tion and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as claimed.

hat is claimed as new is:

1. A device of the class described comprising a threaded shank, pairs of laterally extending parallel ears at one end of the shank, arms pivoted between the ears, means to normally tend to force the arms outwardly, a bushing comprising screw threads and adapted to be threaded onto the shank and coo erative with saidarms to secure the shan to a support and a nut adapted to be screwed onto said shank and cooperative with said head for securing an object to be supported to said shank.

2. The combination of a wall, a threaded shank, arms pivoted to one end of the shank, means to normally tend to force the arms outwardly, the shank being adaptedto be passed through an opening in said wall, the arms when extended being adapted to engage the inner face of the wall, the outer face of the wall being provided with a counter-sink, a flanged bushing comprising screw threads and adapted-to be threaded on the shank, the flange of the bushing resting in the countersink and adapted to cooperate with the arms/in securing the bolt in place, and a nut adapted to be screwed on the shank and adapted to cooperate with said arms of said bushing to removably secure an article against the wall.

3. In a device of the class described, the combination of a wall, a bolt having a screw threaded shank, arms pivotally mounted on said bolt at one of its ends, springs normally tending to move said arms outwardly, said bolt being adapted to be passed through an opening in said wall whereby said arms when extended may engage the inner face of the wall, the outer face of the wall being provided with a counter-sink, a flanged bushing provided with screw threads and having its flange provided with means for screwing said bushing onto the screw threaded shank of said bolt so as to seat said flange in said counter-sink and to cause said flange and arms to hold said bolt securely against movement in either direction longitudinally of its axis, and a nut adapted to be screwed on said screw threaded shank for securing an article to be supported to said bolt.

In testimony whereof I have afiixed my signature THOMAS DOWD.
